What were also known as the "freedom wars" to the ancient greeks?

The wars that the ancient Greeks fought against the Persians, who were seen as savages or barbarians by Greek culture, were also called Wars of Freedom. These wars were supported, according to the Greek belief, by the Gods, who were also Gods of Liberty, and this formed a link between Greek politics and their religion. The Greeks, after the Persian Wars, or Wars of Freedom, were strongly related to Zeus and Artemis, for they protected the Greek Freedom, called Eleutheria, or the personification of freedom. Being the ancient Greece where the first experiment of human freedom was made, the mixture of religion and politics around Freedom, was a very important element in the culture of ancient Greece.
